Experimental values of density and speed of sound for binary liquid mixtures of 2,5-dimethylfuran (2,5-DMF) with furfuryl alcohol (FA), methyl isobutyl ketone (MIBK), 1-butanol and 2-butanol and over the entire composition range of 2,5-DMF and at the temperature range of 293.15–323.15 K at 10 K intervals and at pressure p = 0.1 MPa were reported. Experimental data were used to assess the thermodynamics properties of studied mixtures. These properties were used to interpret the molecular interactions among component of liquids. The values of excess/deviation functions have been fitted to Redlich−Kister type polynomial equation. From the obtained results, a discussion was carried out in terms of nature of intermolecular interactions and structure factors in the binary mixtures.

Temperature dependence of saturated vapour pressures of methyl isobutyl ketone, diisobutyl ketone, 1,1-difluorotetrachloroethane, and 1,2-diflurotetrachloethane was measured. A static method was used, and the measurements were carried out in the temperature range of 261 to 353 K and in the pressure range of 0.5-49 kPa.

The densities, viscosities and ultrasonic velocities of binary liquid mixtures of Isopropyl alcohol with acetophenone and methyl isobutyl ketone (MIBK) have been measured at temperatures 298.15 and 308.15 K over the entire range of mole fraction. From these data, acoustical parameters such as adiabatic compressibility (β), free volume (Vf) and free length (Lf) have been estimated using the standard relations. The results are interpreted in terms of molecular interactions present in the mixtures.
